Abstract

The invention discloses an oil cylinder rod self-locking sleeve device used in a foundation pile self-balancing load detection load box. The oil cylinder rod self-locking sleeve device comprises a sleeve base with a notch, cushions are arranged along the two sides of the notch in the sleeve base and provided with semicircular expansion rings, capsules in which high-strength bonding liquid is packaged are arranged between the two sides of the notch of the sleeve base and the semicircular expansion rings, two front wedges are arranged between the capsules, and a miniature cylinder body is arranged between the two front wedges, internally provided with a plunger and a seal ring and externally connected with an input mouth; a capsule in which high-strength bonding liquid is packaged is arranged at the position opposite to the notch of the sleeve base, and a rear wedge is arranged between the capsule and the sleeve base. The oil cylinder rod self-locking sleeve device is specially used for solving the uplift problem after an oil cylinder of the self-balancing load box completes work, an oil cylinder rod stretching out to any appointed position can be locked, and the oil cylinder rod self-locking sleeve device is suitable for self-locking of the load box oil cylinder rod in the foundation pile self-balancing load detection process.

Description

technical field [0001] The invention relates to a self-locking device, in particular to an oil cylinder rod self-locking set used in a load box for foundation pile self-balancing load detection. Background technique [0002] Due to the rapid development of the national economy, my country's infrastructure construction continues to heat up, and a large number of super high-rise buildings and super-large highway bridges have started construction. The requirements for the bearing capacity of pile foundations are also getting higher and higher. The limit value of pile bearing capacity exceeds 100000kN. In the past, the conventional single pile static load test detection method obviously cannot meet the detection requirements (the vertical ultimate bearing capacity of a single pile detected by the surcharge method generally does not exceed 20,000kN, and the vertical ultimate bearing capacity of a single pile detected by the anchor pile reaction method generally does not exceed 50,...
